Cygnus 3 Thickness Gauge
The Cygnus 3 Multiple-Echo Ultrasonic Thickness Gauge is a
rugged, handheld, battery-powered instrument designed for high-
reliability thickness measurement using the multiple-echo
technique.
The Gau
ge can be used with a choice of single-crystal Ultrasonic
Probes, depending on the thickness and type of material that is to
be measured.
Measurements can be displayed in Metric (mm) or in Imperial
(inch) units and measurement resolution can be selected for either
0.1 or 0.05 mm, (0.005 inch or 0.002
inch). The Gauge has a large
LCD which can be easily read in sunlight and in low-light situations
using a white LED backlight.
The Gaug
e has the facility to record thickness measurements to
internal Flash memory, these measurements can be easily
transferred to a computer via a USB connection which then can be
used to generate survey reports.
Crystal-controlled Calibration provides stability and accuracy. The
Gauge can easily be calibrated to a known thickness or to a known
Velocity of Sound. Velocity of Sound is displayed in either m/s or
in/μs, depending on the current selection for Measurement Units.
The Gau
ge is able to operate accurately in a wide range of ambient
temperatures and is environmentally sealed to IP65 for use in wet
or dusty conditions.
The Gau
ge is a solid-state electronic instrument which, under
normal operating conditions, will give many years of active
service.
Although designed for ease of operation the first time user
should carefully read this manual to familiarise themselves
with the features of the Gauge.
